Karen Horney's Theories of Personality argued that childhood social tensions were crucial for personality formation. Sigmund Freud believed that childhood sexual experiences shaped personality formation. Horney believed that anxiety in childhood triggered or caused the need for love and security. Freud said that the unconscious mind and desires influenced personality. Horney countered or argued against Freud's psycho sexual theory of "penis envy" and women's weak superegos. They both agreed on the Id, Ego, and Superego, the personality is shaped during childhood, and the dynamics of anxiety and defense mechanisms.
